Simi Valley Public Library Roof Rehabilitation Project, Cp25000001

The City of Simi Valley is seeking bids for the roof rehabilitation of the Simi Valley Public Library, a project involving the installation of a cool roof system over approximately 35,000 square feet of existing roof area. The scope of work includes the removal of gravel and damaged roofing layers, repair of the roof deck, and installation of a new 80-mil thermoplastic polyolefin (TPO) roofing system with insulation and cover board, along with replacement of all flashings, sheet metal, and related components. Additionally, 2,250 linear feet of curtain wall sealant must be removed and replaced. The work must comply with ASTM standards for leak detection and hydrostatic testing, manufacturer specifications, and OSHA safety regulations, with all materials delivered in original sealed containers and stored in dry, weather-protected areas. The project requires a mock-up approval, successful leak-free performance testing, and submission of warranties, environmental documentation, and quality control reports. The contractor must perform at least 50% of the work directly and is responsible for all inspection coordination, corrections, and compliance with city specifications. The contract is structured as a firm-fixed-price arrangement with a lump sum base bid and unit price items, though the only confirmed cost is $70,000 for additional worksite remediation; other line items are listed without unit prices, making the total contract value uncertain. The period of performance is capped at 45 calendar days from the Notice to Proceed, which must be issued within 15 days of contract award. Bids must be submitted by August 27, 2026, in sealed form to the City Hall address, with electronic submissions required only for as-built drawings. Proposals are limited to 20 pages and must include bid security, a non-collusion affidavit, and a bid bond. The award will be made on a lowest price technically acceptable basis, requiring full compliance with mandatory technical and administrative requirements. The contractor must maintain three years of professional liability insurance naming the city as an additional insured, submit shop drawings three weeks prior to installation, and obtain written approval before any material substitutions. All work will be inspected and accepted on-site by the City’s Public Works Director, who retains final authority over compliance and acceptance.
